Cisplatin vs Carboplatin in Extrapulmonary Poorly Differentiated Neuroendocrine Carcinomas (PD NEC)

McLaughlin Nicole , McGarrah Patrick , Eiring Rachel , Leventakos Konstantinos , Sonbol Mohamad , Starr Jason , Hobday Timothy , Halfdanarson Thorvardur

Background: Extrapulmonary PD NECs carry a poor prognosis. Some studies suggest cisplatin is more appropriate for younger patients due to its increased potency and nephrotoxicity compared to carboplatin, but randomized trials are lacking. We aim to determine whether there is a difference in outcomes for cisplatin vs carboplatin while adjusting for possible confounding factors.Methods: We identified PD NEC patients at Mayo Clinic between 2000-2022.

Cabozantinib as salvage therapy for well differentiated grade 3 neuroendocrine tumors (G3 NETs)

Schnell Rylie R. , Eiring Rachel A. , Miller Morgan C. , McGarrah Patrick W. , Halfdanarson Thorvardur R.

Background: G3 NETs are a recently recognized entity and although the treatment recommendations largely follow those for grade 1 and 2 NETs, the outcomes of therapy are inferior. Little is known about the optimal therapy sequencing but small studies have suggested a benefit of multikinase inhibitors. Somatostatin analogs, PRRT and chemotherapy have all been reported to have activity but later lines of therapy are needed. In this study, we sought to evaluate the activity of cab...

Background: Lu177 has shown efficacy in advanced NET with significant hematologic toxicity, including therapy-related myeloid neoplasm (t-MN). CH is defined by acquisition of somatic mutations in hematopoietic stem cells with potential for expansion over time. In this study, we aimed to assess the prevalence of CH in NET patients (pts) prior to Lu177 along with the incidence of cytopenia in NET pts treated with lu177 based on the CH status at baselineMet...
